This guide details the operation of the US M3 37mm Anti-Tank Gun, as demonstrated by Ian McCollum of Forgotten Weapons. It covers the manual breech operation, loading procedure, aiming with handwheels, firing mechanism, and spent casing extraction. The M3 is presented as a simple, single-shot, towed artillery piece effective early in WWII but quickly outmoded.

Quick Summary

The US M3 37mm Anti-Tank Gun operates via a manual sliding block breech, requiring operators to load each 37mm cartridge by hand, close the breech, aim using traverse and elevation handwheels, and manually extract spent casings. This simple, single-shot design was effective early in WWII but became obsolete against heavier armor.
